ABSTRACT:
A prosthetic wrist implant and method for implanting the wrist implant. The prosthetic wrist implant is disposed between a patient's radius and carpal complex bones. It includes a radial implant component having an elongated concave articulate front surface and a post member projecting from the back of the radial implant into the cavity of the radial bone. A carpal bone implant includes a planar member with a front face and a flat rear face and a second post member projecting from the rear face into a cavity of the carpal bone complex. An articulating bearing member has a flat bottom surface fastened to the front face of the planar member and an elongated convex surface slidingly engaging the concave articular surface of the radial implant to permit articulation between the radial and carpal bones.
